Inflation in retirement

Why inflation matters more in retirement

Retirement spending often lasts 25 to 35 years, which gives inflation plenty of time to erode purchasing power.

Even modest long-run inflation can materially change what a fixed dollar amount actually buys.

It helps to separate nominal returns from inflation instead of mixing them loosely.

That makes it easier to compare assumptions and understand what is happening inside the model.

Inflation is not a side note in retirement planning. It is one of the main forces any long-horizon withdrawal plan needs to respect.
